IPsec Virtual Private Network
Fundamentals provides a basic working knowledge of IPsec on
various Cisco routing and switching platforms. It provides the
foundation necessary to understand the different components of
Cisco IPsec implementation and how it can be successfully
implemented in a variety of network topologies and markets (service
provider, enterprise, financial, government). This book views IPsec
as an emerging requirement in most major vertical markets,
explaining the need for increased information authentication,
confidentiality, and non-repudiation for secure transmission of
confidential data. The book is written using a layered approach,
starting with basic explanations of why IPsec was developed and the
types of organizations relying on IPsec to secure data
transmissions. It then outlines the basic IPsec/ISAKMP fundamentals
that were developed to meet demand for secure data transmission.
The book covers the design and implementation of IPsec VPN
architectures using an array of Cisco products, starting with basic
concepts and proceeding to more advanced topics including high
availability solutions and public key infrastructure (PKI). Sample
topology diagrams and configuration examples are provided in each
chapter to reinforce the fundamentals expressed in text and to
assist readers in translating concepts into practical deployment
scenarios. Additionally, comprehensive case studies are
incorporated throughout to map topics to real-world solutions.
